2 About DNV GL On 12 th September 2013, Det Norske Veritas (DNV) and Germanischer Lloyd (GL) merged to form DNV GL We are today the world s largest ship and offshore classification society the leading technical advisor to the global oil and gas industry a leading expert of the energy value chain, including renewables and energy efficiency one of the world s top three certification bodies 2

3 Renewables certification f Accredited certification of equipment (products), services and projects in renewable energy Component certification Prototype certification Type certification Project certification Onshore wind Offshore wind Wave and tidal Solar/PV Certification is based upon: Internationally accepted standards Various national certification systems DNV GL standards and guidelines 5

4 Commercialisation of the marine renewables Solving the energy trilemma? Affordability? 6 Reliability Sustainability

5 What is Certification? The Certification Process Do they match??? Photo: Voith Technical requirements Photo: Tocardo 7 22 February, 2017

6 Basic marine renewables certification elements Design Assessment Test Survey and Quality Control Plausibility of the design Protection and safety Loading Structural analysis Mechanical & electrical installation Examination of drawings Examination of components Model tests Component tests Test of the prototype Comparison of test results with assumptions Examination of fabrication quality Witnessing of installation Witnessing of commissioning Image: Atlantis Photo: Coast Plymouth Univ.
